Aside from being just a standard proximity beacon, it can also monitor temperature, humidity, air pressure and acceleration, and can be easily adjusted to cover different kinds of needs without programming or electronic knowledge. The device can operate for several years on a single coin battery.
Flashing the device doesn't require wires, however all the necessary pins and buses are still available for serious evaluation. You can check out the hardware GitHub repository for more information.
The device could potentially be used for a large number of things, such as to monitor weather or even as a device to warn you when something is moved, such as a bicycle.
The project is heading to KickStarter soon, but more information (including technical specs) can be found at ruuvitag.com
